\[\left\{ \begin{matrix} y - x = 2\ \ \ \ \ \\ 2y - 2x = 5 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} y = x + 2\ \ \ \ \ \\ 2y = 2x + 5 \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} y = x + 2\ \ \ \\ y = x + 2,5 \\ \end{matrix} \right.\ \]

\[y = 2 + x\]

\[x\]	\[0\]	\[1\]
\[y\]	\[2\]	\[3\]

\[y = x + 2,5\]

\[x\]	\[0\]	\[2\]
\[y\]	\[2,5\]	\[4,5\]

\[Ответ:нет\ решений.\ \]
